Microchip LX7167CLD-TR

Manufacturer No:

LX7167CLD-TR

Manufacturer:

Microchip

Package:

8-WFDFN Exposed Pad

Description:

LX7167 is a step-down PWM Switching Regulator IC with integrated high side P-CH and low side NCH MOSFETs. The IC operates using a hysteretic control topology with a full load operating switching frequency of 3MHz allowing small output filter components while maintaining excellent dynamic load response. The operational input voltage range of LX7167 is from 3V to 5.5V. The part has a Power Save Mode (PSM) that automatically transitions between PWM and PSM mode depending on the load current. This allows the converter’s efficiency to remain high when load current drops. There is a Power Good function to indicate the status of the IC. In the shutdown mode, the IC’s current consumption is reduced to less than 1\u0026#181;A and the output capacitor is discharged. Other features of the part are: a) Cycle-by-cycle current limit followed by HICCUP mode which reduces the overall power dissipation of the internal MOSFETs, b) thermal protection and internal digital soft start. The LX7167 is available in a 2mm x 2mm 8 pin exposed pad DFN package.

This allows the converter’s efficiency to remain high when load current drops. There is a Power Good function to indicate the status of the IC. In the shutdown mode, the IC’s current consumption is reduced to less than 1µA and the output capacitor is discharged. Other features of the part are: a) Cycle-by-cycle current limit followed by HICCUP mode which reduces the overall power dissipation of the internal MOSFETs, b) thermal protection and internal digital soft start. The LX7167 is available in a 2mm x 2mm 8 pin exposed pad DFN package.
